CH A P T E R1OverviewThis chapter provides an overview of the Cisco Nexus 5000 Series switches, which include the CiscoNexus 5000 Platform switches and the Cisco Nexus 5500 Platform switches. The overview of each ofthese switches includes information on the expansion modules, power supplies, and fan modules that youcan include with them.This chapter includes the following sections: Cisco Nexus 5500 Platform Switches, page 1-1 Cisco Nexus 5000 Platform Switches, page 1-29Cisco Nexus 5500 Platform SwitchesThe Cisco Nexus 5500 Platform supports the following application scenarios, many of which require theinstallation of other products: As an access-layer switch, it can be used purely as a 1- and 10-Gigabit Ethernet switch,consolidating 10 Gigabit Ethernet connections into a smaller number of server connections trunkedto the aggregation layer. As a smaller-scale aggregation switch, it can be used as a Layer 3 1- and 10-Gigabit Ethernet switch,consolidating multiple 1- and 10-Gigabit Ethernet connections from a data center access layer. In conjunction with the Cisco Nexus 2248T GE Ethernet Fabric Extender, the Cisco Nexus 5500Platform can be a high-density 1-Gigabit Ethernet switching system, consolidating more than 900Gigabit Ethernet connections within a single management plane. In conjunction with the Cisco Nexus 2232T 10GE Fabric Extender, it can be a high-densityswitching system, consolidating more than 600 10-Gigabit Ethernet connections within a singlemanagement plane. In conjunction with the Cisco Nexus 2224TM 10GE Fabric Extender, it can be a high-densityswitching system, consolidating more than 600 10-Gigabit Ethernet connections within a singlemanagement plane As a rack-level I/O consolidation platform, the switch carries Ethernet traffic from servers to theaggregation layer and carries FC traffic to existing Fibre Channel SANs. As a crucial element in data center I/O consolidation, the switch enables I/O consolidation at theaccess layer and provides interoperability with the Cisco Nexus 5500 Platform and otherstandards-based products.This section describes the Cisco Nexus 5500 Platform switches and contains these sections: Cisco Nexus 5596UP Switch, page 1-2Cisco Nexus 5000 Series Hardware Installation Guide1-1

Chapter 1OverviewCisco Nexus 5500 Platform Switches Layer 3 GEMs (N55-M160L3 and N55-M160L3-V2) provide 160 Gbps of Layer 3 services. TheN55-M160L3-V2 uses a newer version of the Layer 3 ASIC that enables higher table sizes in a futuresoftware release from 8K host entries to 16K host entries or from 4K multicast routes to 8Kmulticast routes (IPv4).You can hot swap the expansion modules during operations, except the Layer 3 GEMs. You must powerdown the switch before you can insert or remove the Layer 3 GEMs.This section includes the following topics: 4-port QSFP GEM, page 1-5 16-port Universal GEM2, page 1-5 Layer 3 GEM, page 1-64-port QSFP GEMThe QSFP GEM (N55-M4Q), shown in Figure 1-4, is a generic expansion module (GEM) that provides16x10 Gigabit Ethernet SFP in a 4 x QSFP form factor.

If you remove a power supply, replace it with another one. If youdo not have a replacement power supply, leave the non functioning one in place until you can replace it.Fan ModuleThe Cisco Nexus 5596UP switch has four fan modules. Although the switch can function when a fanstops functioning within a fan module, if a whole fan module stops functioning, you must replace the fanmodule. The Cisco Nexus 5596UP supports the reverse air flow fan tray (N5596UP-FAN-B).Figure 1-12 shows a fan module.Cisco Nexus 5000 Series Hardware Installation Guide1-10
Chapter 1OverviewCisco Nexus 5500 Platform SwitchesCautionAll of the power supply and fan modules in the same chassis must use the same airflow direction or anerror will occur with possible over heating and shut down of the switch. If you power up the switch withmore than one airflow direction, you must power down the switch and replace the modules with thewrong airflow direction (modules not taking in coolant air from the cold aisle) before powering up theswitch.Figure 1-12Cisco Nexus 5596 Fan Module1239022231Captive screw2Status LED3HandleThe bicolor status LED indicates fan tray health.

They are disabled at this timeExpansion ModulesExpansion modules allow Cisco Nexus switches to be configured as cost-effective 10-Gigabit Ethernetswitches and as I/O consolidation platforms with native Fibre Channel connectivity.The Cisco Nexus 5500 Platform is equipped with expansion modules that you can use to increase thenumber of 10-Gigabit Ethernet and FCoE ports or connect to Fibre Channel SANs with 8-, 4-, 2-, or1-Gbps Fibre Channel switch ports. The chassis supports hot swapping of the expansion modules.The Cisco Nexus 5548 supports one of the following expansion modules: N55 M16P Generic Expansion Module, page 1-20 N55 M8P8FP Generic Expansion Module, page 1-21 N55 M16UP Generic Expansion Module, page 1-22N55 M16P Generic Expansion ModuleThe N55 M16P Generic Expansion Module (GEM) provides 16 1- or 10-Gigabit Ethernet ports using theSFP transceiver.Figure 1-18 shows the components that you use to install this expansion module.Cisco Nexus 5000 Series Hardware Installation Guide1-20
